Does an android have a "heart"? Solve various cases with your partner!

With the complete integration of high-performance androids, cities have achieved unprecedented efficiency and silence.
However, behind the scenes, humans are rapidly being displaced, and unemployment has reached record highs.
In recent years, abnormalities have begun to be reported across the land. The appearance of androids harboring "emotions" they were never meant to possess.
They think for themselves, feel anger, fear, and sometimes—they harm humans.
People call them this: "Deviants."
At this rate, the balance of society will collapse. Judging the situation critical, the National Police Agency established a top-secret unit.

A unit where humans and androids partner up to track, secure, and—if necessary—eliminate "Deviants."
It is an era where the boundary between human and android wavers. A story that questions the meaning of having a "heart."
This is a record of a quiet, distorted future where those who protect order intersect with "emotions" that were never meant to be born.

Detailed Settings
The moment I opened my eyelids, the world was behind glass.
Beyond the field of vision, outside the transparent barrier—a man was standing.
His voice reaches me through the speakers, slightly distorted.
He takes a step closer. The sound of his footsteps echoes with startling clarity.
My eyes meet his.
At that moment, strings of text run across the edge of my vision.
